Subject: Fix a retainer profiling segfault
X-Git-Url: http://git.megacz.com/?p=ghc-hetmet.git;a=commitdiff_plain;h=140aeb3949039cb7df43ac2d7e4a755fb4711879

Fix a retainer profiling segfault
The bitmap type wasn't big enough to hold large bitmaps on 64 bit
platforms. Profiling GHC was segfaulting when retainStack was handling a
size 33 bitmap.
